The first one looks good, sharp, good contrast. I've always like Tokina lenses, I used to have a 12-24 f/4, it was a very good lens, when I purchased my 5D I sold it, my 17-40 had close to the same UWA range then.

@ Don, whoa! Camera shake with a Sony with SSS???? Cmon I thought this was a thing of the past! I thought that's why all of us should switch to Sony, blurry photos due to camera shake will be a thing of the past...

Actually Frank it looks like a little bit of back focus, the feathers on his wing are pretty sharp.

Keep that DOF in mind...

With a long telephoto shot, you have to be cognizant of the Depth of Field (DOF). You guys know that. Heck, it is razor thin with the 135mm @ f/1.8

I suggest running the numbers in the DOF calculator and get comfortable with what it takes to get a "foot" of focal depth out of the lens at 400mm. Remember, this is also a "crop" camera, not a FF. Select: "A700, A550, A500, A450"

From what I have determined, @ 400mm... your aperture would have to be f/22 and you would have to be back to about 25-feet!

At 100mm, things are a little more generous, with and aperture of f/8 and only 10-feet away. Zooms have their limitations when you have a chubby, 3D target and it want it in focus, front-to-back.

Thanks for the photography lesson, Don...This little exercise shows that SSS is just a very small part of having this stuff all work out. There are many other determining factors with steadiness just being one of them. Thanks Frank for having the nuts to post this shot. Sony cameras miss shots too....or is it the photog behind the camera? Nothing against you, Frank, I have have a trash basket full of missed this or that, I think we all do.

I think Peter is right. There is always a lesson to be learned. If I didn't post this I would have thought it was camera shake. I do have a steady hand. Almost all my images are hand held. I always check the SSS meter before I take the shot. I will check the DOF chart. The EXif for that image was iso 400, f/8, 1/1250 at 200mm.
